In this batch study, the adsorption of malathion by using granular activated carbon with different parameters due to the particle size, dosage of carbons, as well as the initial concentration of malathion was investigated. Batch tests were carried out to determine the potential and the effectiveness of granular activated carbon (GAC) in removal of pesticide in agricultural run off. The granular activated carbon; coconut shell and palm shells were used and analyzed as the adsorbent material. The Langmuir and Freundlich adsorption isotherms models were applied to describe the characteristics of adsorption behavior. Equilibrium data fitted well with the Langmuir model and Freundlich model with maximum adsorption capacity of 909.1mg/g. The results indicate that the GAC could be used to effectively adsorb pesticide (malathion) from agricultural runoff.
在这项批处理研究中,研究了由于粒径、碳剂量以及马拉硫磷初始浓度的不同,颗粒状活性炭对马拉硫磷的吸附作用。进行了批量测试,以确定颗粒状活性炭(GAC)在去除农业径流中农药方面的潜力和效果。使用并分析了椰壳和棕榈壳颗粒状活性炭作为吸附材料。应用 Langmuir 和 Freundlich 吸附等温线模型来描述吸附行为的特征。平衡数据很好地符合 Langmuir 模型和 Freundlich 模型,最大吸附容量为 909.1mg/g。结果表明,GAC 可有效吸附农业径流中的农药(马拉硫磷)。
